Summary of Bioretention Variants for Permeability of Native Soils and Potential Land use Pollutant Loading
(Link to this table)
| Bioretention Type1 | Variant | Underlying Soil Performance Criteria |
|---|---|---|
| Bioinfiltration (Infiltration/Recharge Facility) |
No underdrain | Higher recharge potential (facility drain time without underdrain is 48 hours or less) |
| Biofiltration with underdrain at the bottom (Filtration/Partial Recharge Facility) |
Underdrain | Lower recharge potential (facility drain time without underdrain is > 48 hours) |
| Biofiltration with internal water storage | Underdrain | Lower recharge potential (facility drain time without underdrain is >48 hours) |
| Biofiltration with elevated underdrain (Infiltration/Filtration/Recharge Facility) |
Elevated underdrain | Higher nutrient loadings and/or quantity control |
| Biofiltration with liner (Filtration Only Facility) |
Underdrain with liner | Hot Spot Treatment |
